I entirely agree. I think the slide from the network 'stack' to
'stackable networks' introduces a very nice abstraction, that you can soft
reconfigure any (apparent) n-way end-to-end configuration on top of any
other, for some cost in packet overhead, delay, etc.
Does it introduce much complexity in a router to hold two or more models of
network routing? is this the kind of thing virtual routers inside one crate
Actually, I think that might also point to the geographic
addressing model as having some usefulness as well: if we explicitly expect to
have to do layered networking, then we might as well make the underlying
address topology follow the beaurocracy. Another unpopular proposal for IPv6
dropped by the wayside...
